WE propose that the relative cross sections for the reaction processes {eta}{ital p},{eta}{prime}{ital p}{r arrow}{eta}{ital p},{eta}{prime}{ital p},{ital K}{sup +}{Lambda} and {pi}{sup {minus}}{ital p}{r arrow}{eta}{ital n},{eta}{prime}{ital n}, induced by pseudoscalar mesons on a proton target, provide a sensitive test for the presence of a strange-antistrange ({ital s{bar s}}) quark component in the nucleon's wave function.
